Skidbladner

Skidbladner, in Norse mythology, was a splendid ship belonging to the god Frey. It was built by skilful dwarfs, the sons of Iwald, and was made large enough to hold all the asas with their armor, but is nevertheless capable of being reduced to so small dimensions that it may be carried away in one's pocket. It also commands favorable winds, whatever may be the destination of its voyage.
